Last Updated: 10th November 2022 · Written by Kate Young

Are you looking to revolutionise your diet after allergy or intolerance testing? Vitamins (along with minerals) are required for essential body function and cannot be synthesised in the body, therefore they must be taken in through the diet. Vitamins provide the key to unlocking and using macronutrients for a specific purpose in the body. For example, B vitamins are required to produce energy for the body and a deficiency of this nutrient can result in fatigue.

Vitamins are either water-soluble or fat-soluble, meaning they require this substance to be present in order to absorb them. Everyone has a different level of requirement of vitamins due to different life stages, physical activity, health conditions, and medications however what is important for everybody is a good range of nutrient-dense food to provide a constant supply of vitamins for health and optimum function.
